CDC發新指引 完成疫苗接種戶外可不戴口罩

聯邦疾病防治中心(CDC)今天宣布,完成新冠疫苗接種者(fully vaccinated),可不戴口罩外出散步、慢跑、騎車,或與友人在戶外就餐,對於未接種者,CDC仍舊建議外出在公共場所戴口罩。

根據CDC的定義,接種輝瑞或莫德納疫苗第二針的兩周後,或是接種強生疫苗的兩周後,才算「完成接種」;目前全美有超過42%的人口至少接種一劑,近30%人口完成接種。

CDC主任瓦倫斯基(Rochelle Walensky)27日在白宮疫情簡報會公布這一最新口罩指南,表示已完成接種者,可不戴口罩外出參加戶外小型聚會,即便其中有人打了疫苗、有人沒打;並可在不戴口罩的情況下,與來自不同家庭的友人在戶外聚餐。

而在一些人潮擁擠的戶外公共場所,或是商場等室內公共場所等,即便完成接種也應該戴口罩。

許多研究一致表明,戶外傳播新冠病毒的風險大大降低,尤其當人們保持社交距離時;也不斷有衛生專家質疑,在越來越多美國人接種疫苗的當下,戶外是否還需要戴口罩。

CDC重申,儘管更新了戴口罩的建議,但最終選擇在於個人,在決定不戴口罩就外出之前,應先考慮自身情況,以及對他人的風險。
